DOOR FOR S TOVES.

EIPEOIFICATION forming part of Letters Patent No. 544,772, dated August20, 1895.

Application filed June 18,1395- Serial No. 553,264. (No model- To allwhom it may concern.-

Be it known that I, JOSEPH SCHILL, a citizen of the United States, and aresident of the city of Orestline, in the county of Craw-- ford, in theState of Ohio, have invented certain new and useful Improvements inDoors for Stoves, of which the following is acorrect description.

The object of the invention is to provide, in that class of double doorsor twin doors for stove or range ovens which are hinged in a horizontalplane one above the other, and which in opening or in closing move inopposite directions, a simple and inexpensive means whereby the twodoors and their connections operate to balance and mutually support eachother when adjusted, whether in their open or in their closed positionin relation to the oven to which they are applied.

The invention consists in the application of an elbow-lever, or of twocoincident connected elbow-levers, within an oven or other chamber of astove or range, and the connection of the two arms of such lever orlevers with the upper half-door and with the lower half-door, in suchmanner that the half-doors or twin-doors shall balance or counterweighteach other in whichever position they may be adjusted. t

The invention consists also in various novel combinations of elements inor in connection with a stove or other oven, which will first bedescribed with particular reference to the details of construction, andthen specifically and distinctly summarized in the concluding paragraphsof this specification.

-In the accompanying drawings, which constitute a part of'this specificdescription, Figure 1 represents a sectional view, partly in elevation,of the oven of a stove or range in which my improved twin-doors orhalf-doors and door and oven attachments are provided. Fig. 2 is aperspective elevation showing a duplication .of the lever and a means bywhich simultaneous movement of the two is insured.

. Fig. 3 is a detail showing bearings of the conmeeting shaft or rod.Fig. 4 is a detail representing a modification of that portion of theconnecting attachments which supports the lower half-door.

It will be apparent that the oven A may be fiexible connection e ticaland closed position.

of the class adapted to bakers use or any oven in an ordinary cookingstove or range.

The two door-sections d and (1 may appropriand is provided upon itsinner surface with.

a lug or eye d Each of thesedoor-sections may have a knob or handle it.

The elbow-levers e may be rigidly secured upon a shaft or rod 7', one ateach end thereof, just within the projecting journals r (not shown,)which are received in the coincident bearings a b in the side walls a ofthe oven, Fig. 2; or a single lever may be secured by a pivot-pin 10 inthe upper front portion of such walls, as shown in Fig. 1; or, ifdesired, the elbow may be pivoted between two parallel lugs a a whichproject downwardly from the upper wall or top plate a of the oven.

The lower or inner arm 6: of the elbow lever or levers e is connected byan arm 6 to the lug or eye-d upon the half-door 01 or it may, as in Fig.4, be connected thereto by a The upper arm a of the lever e is arrangedat such an angle with the arm e of the lever that when the lowerhalf-door d is moved downwardly the inner portion of the arm a will bearby its upper face or edge against the upper margin of the door-opening,while theouter extremity of the arm will bear against the under andinner face of the upper halfdoor and cause it to be gradually elevatedto its horizontal and open position, in which position the Weight of thelower half-door and its connections will serve to maintain it. Thedescribed operation being and the weight of the upper half-door and ofthe arms 6 with which it is in contact will then maintain the lowerhalf-door in its ver- It will be understood that the two duplicateconnected levers will be employed in ovens of considerable dimensions,and that in small ovens a single lever may be found sufficientp Theinvention having been thus described, what is claimed is 1. Thecombination with an oven, of an upper half-door and a lower half-doorwhich are adapted in opening or in closing, to move in a vertical plane;and elboW-levers,-one, or two connected together,which arepivotallysecured upon an inner portion of the oven, one arm of eachlever being operatively-connected to the lower half-door, and the otherarm of the lever or levers being adapted to support the upper half-doorwithout positive mechanical connection therewith.

2. The combination with an oven, of an upper half-door which by itsupper edge is hinged at the upper extremity .of the oven-opening; alower half-door which is provided with an inner lug or eye, and which byits lower edge is hinged at the lower extremity of the ovenopening; anelbow'lever which at its angle is pivoted upon an upper, front, interiorportion of the oven, and which by one arm rests in contact with theupper half-door of the oven; and a supporting-connection between theother arm of the lever, and the lower halfdoor.

3. In an oven, an upper half-door and a lower half-door which areadapted to be moved oppositely, to close or to unclose the oven; anelbow-lever which is pivotally-secured to an upper portion of the oven,which by one arm bears against the inner face of the upper halfdoor, toopen the same or to permit it to close, and which by its other arm issupportinglyconnected to the lower half-door;-in combination.

4. An oven which is provided with upper and lower oppositely-movinghalf-doors which meet at their free edges to close the doorway,

and with an elbow-lever which is pivotallymounted in the inner upperportion of the oven;--which by one arm loosely supports the upperhalf-door, and by its opposite arm and an intermediate connection,supports the lower half-door;--w hereby when the halfdoors are closedthe upper half-door serves to maintain the lower half-door in its closedposition,and whereby when the half-doors are open, the lower half-doorserves to maintain the upper half-door in its open position.

5. In an oven, the combination of two oppositely-moving half-doors whichmeet in a horizontal plane to close the oven; elbow-levers,one, ortwo,rigidly connected for operation as one,-which at their angle arepivoted to an upper, front, interior portion of the oven, one arm ofwhich is in supporting contact with the upper half-door, and theopposite arm of which is provided with a supporting-connection with thelower half-door.

6. The combination with an oven, of an elbow-lever which is mountedwithin the oven;

and upper and lower half'doors which move oppositely, and which areconnected to the lever, substantially as described, so that one of thehalf-doors shall counterweight the other, in whichever position they maybe adjusted.

7. An oven which is provided with oppositely-moving half-doors whichunite to close the opening of the oven; and which is provided also witha lever which is pivotallymounted Within the oven, and which when eitherof the half-doors ismoved to close the oven, operates to cause or topermit the closure of the other half-door also.

In testimony whereof I have hereunto affixed my signature this 8th dayof June, 1895.
